I recently completed installation of a fuel cell, built by Maple Farkles, on my 2015 R1200GSW. This is how I completed fuel-line install which appears to be working well and it allows me to remove the cell in ~15 minutes when I do choose to allow a pillion. I am not including the fuel-cell bracket and cell installation images which varies by personal preference; Mike ships them with instructions specific to your installation-preference/option(s). Feedback and/or recommendations for change/adjustment are requested.

1. Drill 3/4" hole in the bottom, rear, right side of the existing fuel tank and install the bulkhead fitting.
2. Put a piece of mastic tape to protect the frame near the close fitting bulkhead elbow and route the fuel line under the tank to the left side of the bike. NOTE: due to clearance, I have reversed the bulkhead fitting and added an additional gasket(similar to the one visible in the image), flat washer (protects the gasket from the lock washer) and lock washer on the inside of the tank.
3. Route the fuel line under the frame, and place the quick disconnect, on the left side and up to where it will attach to the fuel cell. (this will be hidden in a future step)
4. Install the petcock to the newly routed fuel line and attach the breather hose to the filler neck. NOTE: the fuel breather line is zip tied to my saddlebag rack such that it will discharge behind the rear-wheel rather than on the side as the following two images display; they were taken before that routing was completed.
5. Install a left side Touratech cover to hide the quick disconnect assembly.
6. Install a right Touratech cover to balance and verify that nothing leaks and all works as expected.

NOTE: hose clamps were installed at all connections after the photos were taken.
